Definitions

  • the present invention relates to a method and an apparatus for distributing electronic content, such as electronically stored music or literary works, for example.
  • EBX Electronic Book Exchange
  • the present invention provides an alternative approach to dealing with the issue of unauthorised copying of electronic content by members of the public.
  • One aspect of the present invention lies in an appreciation that unauthorised copying of electronic content may, broadly speaking, be put into two categories: large-scale reproduction of content, by a relatively small number of people and/or organisations for commercial purposes; and the small-scale reproduction of content by a large number of individuals for private consumption.
  • the former activity is typically performed by organised crime for commercial motives, and is therefore unlikely to be prevented by the continual production of increasingly complex technological measures, whereas the latter is frequently an activity motivated by a desire to save money, or the desire to share content with members of the same peer group.
  • a consequence of the motives for private copying is that with appropriate incentives, people can be persuaded to acquire legal copies.
  • a first aspect of the present invention provides a method of distributing electronic content comprising the steps of:
  • the second consumer will in due course send to the commercial distributor of the content at least sufficient of the second licence data to enable identification of: (a) the content to which it relates, and (b) the status of the second copy.
  • the second consumer then has the chance to purchase the content and send to the commercial distributor of the content payment for the second copy of the content; and subsequent to receipt of payment by the commercial distributor, the commercial distributor will send to the second consumer replacement second licence data including at least replacement status data indicative of the legitimate nature of the second copy of the content, and update the replacement second licence data attached to the second copy of the content.
  • transactions between the first and second consumers on the one hand, and the commercial distributor on the other take place across an information technology network such as the internet.
  • the commercial distributor will be able to determine, upon receipt of temporary licence data, from which full licence holder the content originated.
  • the commercial distributor is then able to reward the full licence holder responsible for transmitting the content. This provides one incentive for consumers to engage in a process of lawful purchase of content, while at the same time benefiting the commercial distributor who has an ad hoc sales force at their disposal.
  • PDA personal digital assistant
  • the commercial distributor operates a content store for each registered consumer, which acts as a form of back-up for copies of content. This provides the consumer with substantial flexibility in the way that they wish to manage their content. For example it obviates the need for them to retain continuously a copy of each piece of content they have purchased, thus providing substantial savings in memory space (e.g. in their PDA's). This is yet a further incentive for consumers to engage in lawful purchase of content.
  • retrieval of content from local storage i.e. storage owned by the consumer
  • the content management program automatically causes connection to the commercial distributor when triggered to do so by one or more predetermined events.
  • One example of such an event is the connection of the PDA to the network, typically via a computer, whereupon the content management program dispatches all licence data to the commercial distributor for the distributor to vet for temporary licences or anomalies, such as licences with ID numbers which do not correspond in the records of the commercial distributor to the content in respect of which they have been issued.
  • content such as music, literary or dramatic works, films or other moving images, or indeed any artistic or other work whatsoever which is at some stage converted into electronic form to enable its consumption by a consumer (i.e. "electronic content") is created by Content Providers CP 1 to CP n .
  • the Content Providers CP (which may vary from e.g. a recording artist of world renown to a previously unpublished author) distribute their content through a content distributor 10 (such as a record company), who in turn uses content resellers 12 (such as record shops) to sell content to a consumer 14; on occasions content may also be sold to consumers 14 directly by the content distributor.
  • a commercial distributor Y stores, manages and distributes content from a server 18.
  • the server 18 includes a first memory 20 in which content is stored, and each piece of content is indexed in the content store by an identifier known as a DOI, which is globally unique for a given piece of content, such that all copies of a given piece of content share the same identifier, but different pieces of content will have a different identifier.
  • a DOI identifier
  • One identifier is known as a Digital Object Identifier. From the point of view of the commercial distributor Y it is desirable to keep a record of the number of copies of each piece of content that has been sold; from this the commercial distributor can keep track of which pieces of content are the most popular with their customers.
  • the server 18 of the commercial distributor Y has a further memory called the content ledger 30, which in the present example is simply a character or character string stored in connection with each DOI, and whose instantaneous value is representative of the number of copies of the content identified by the DOI which have been sold.
  • the content ledger 30 simply stores a number X against each DOI, where X is the number of copies sold.
  • the processor 40 of the commercial distributor increments the number X, stored against the DOI of the content which has been sold, by the number of copies sold.
  • a further character or character string Q is added to the identifier DOI n X r , to create a globally unique identifier DOI n X r Q, where Q is a distributor identifier distinguishing commercial distributor Y from every other commercial distributor.
  • This unique identifier DOI n X r Q thus not only identifies the particular purchase, but also the content which was the subject of the purchase and the distributor from whom the content was purchased; further licence states (e.g. indicative of a time-limited licence, or licences that prevent sharing with peers may be provided).
  • the identifier DOI n X r Q is used in a third element of the memory architecture of server 18, known as the user licence directory 50, which is a record of each user registered with the commercial distributor Y, and for each such user, a record of all content sold (and therefore licences granted) to that user.
  • the user licence directory 50 is a third element of the memory architecture of server 18, known as the user licence directory 50, which is a record of each user registered with the commercial distributor Y, and for each such user, a record of all content sold (and therefore licences granted) to that user.
  • users are represented in the licence directory by a user identifier UID, against which a list of identifiers having the form DOIXQ are stored.
  • the user UID A has purchased pieces of content for which licences identified by DOI 1 X 2 Q/F to DOI n X r Q/F have been granted, while user UID B has purchased a piece of content for which a licence identified by DOI 1 X 4 /F has been granted.
  • the final character F is a licence status indicator, and indicates that the licences are full licences as opposed to temporary ones, denoted by the character T.
  • the processor 40 retrieves a copy of the content from the content store 20. This action automatically causes an incrementation of the number X stored in the content ledger 30 against DOI 2 ; in the present example a single copy of DOI 2 has been retrieved, and so X is incremented by one, to the value X p .
  • the user licence directory 50 is then updated to reflect the purchase of DOI 2 by UID A , by adding a record to the directory comprising the user licence identifier DOI 2 QX p /F; the Xpth copy of content DOI 2 , sold by commercial distributor Q with a full licence (F).
  • user licence directory 50 will enable commercial distributor Y to determine that user UID A has purchased a copy of DOI 2 .
  • the user licence directory will also store the time at which the update was made.
  • the user licence identifier DOI 2 QX p /F together with metadata 64 (in this example the title of the artist, the name of the song, and the filename of the file in the content store 20), and a further identifier 66 known as a hash, which together comprise the complete licence data set, are bundled into a message 70 together with content 60.
  • the hash provides a further security measure to ensure that the content is genuinely what it purports to be, and is an identifier such as a character string generated by processing the content itself through a known program.
  • One analogy for the hash is the chassis number on a vehicle ostensibly identified perfectly adequately through the number or licence plate visible to all.
  • the message 70 is then sent via the network, which in the present example is the internet, to the consumer A (whose user ID with commercial distributor Y is UID A ), who downloads the new content 60, and licence data 62 from a desktop computer 80 to a personal digital assistant (PDA) 90.
  • the network which in the present example is the internet
  • the computer 80 is connected to the internet via a LAN card 81, and includes a processor 82 which runs a content management program 84.
  • the content management program 84 stores and retrieves content on hard disc storage 86, and transmits content to the PDA 90 via a communication channel, e.g. a serial bus 88.
  • the PDA likewise includes a processor 92, on which a further copy of the content management program 94 runs, and the processor 92 is connected to the computer via serial port 96, and also to an addressable memory 98.
  • the content management program 94 stores and retrieves content from the addressable memory, and converts it to a form assimilable by the consumer, which in the present example (i.e. the case of music) is then sent to a loud speaker 100 within the PDA.
  • the PDA also has a wireless output 110, typically either Bluetooth or infra red, which enables messages to be beamed over short distances to other PDAs.
  • the two content management programs 84, 94 are adapted to synchronise their activities.
  • the PDA content management application 94 is adapted to retrieve all licence data stored in the memory 98 and to send this to the computer 80 via the serial port 96.
  • the computer content management application 84 When the computer content management application 84 receives such licence data, it is adapted to perform a reconciliation operation, comparing the licence data received from the PDA with the licence data stored within the hard disc storage 86. In the event that new licence data has been transmitted to the computer 80 from the PDA, the computer content management application 84 updates the licence data retained on the hard disc 86 by adding to the hard disc any licence data not already there, and then instructs the PDA content management program 94 to retrieve and send to the computer 80 copies of all content in respect of which new licences have been stored on the computer hard disc 86.
  • the computer content management program 84 is also adapted automatically to connect to the commercial distributor Y, in this example via the internet, upon docking of the PDA to the computer, and to retrieve and send to the commercial distributor all licence data currently held on the hard disc storage 86. Preferably all management activities described above of both content management programs 84, 94 are invisible to the user.
  • content may legitimately be passed directly from one consumer to another, typically using the wireless port 110.
  • consumer "A" instructs the content management program running in PDA 90, via a graphical user interface on the screen 90S of the PDA to beam a copy of a specified piece of content.
  • the content management application running in the PDA 90 retrieves a copy of the content 160, prepares licence data for that content, which in this case includes the licence identifier DOI 2 QX p /T (the "T" denoting a temporary licence status), metadata 202 and the hash 204 for the content, and bundles both into a message 200 which is then transmitted via the wireless port 110 to the PDA 190 of a consumer B.
  • a copy of the content management program is already running on the PDA 190 of consumer B.
  • the content management application is also adapted to transmit a copy of itself to the PDA of consumer B upon instruction from consumer A, and this would occur prior to the transmission of any content.
  • consumer B is now able to consume the content transmitted from consumer A, even though he has not paid for it.
  • the content management programs in the PDA and computer perform the transmission, reconciliation and storage updating operations described above in relation to the licence data and content, causing, inter alia retransmission of the message 200 from the PDA to the computer 180.
  • Docking of the PDA 190 with the computer also causes the content management program to connect via the network to the server 18 of commercial distributor Y, whereupon all the stored licence data held by the computer 180 of consumer B, including that relating to the content beamed to consumer B from consumer A, is sent to the commercial distributor, together with the user identification UID B of consumer B.
  • Illustrated in Fig. 5 is the transmission of message 220, containing the licence data in respect of content acquired from user A; the further licence data which would be transmitted is omitted for the sake of clarity
  • the server of commercial distributor Y Upon receipt of the licence data sent by computer 180, the server of commercial distributor Y performs a reconciliation operation, comparing the licence data received with the licence data which is held in the user licence directory 50 against user identification UID B . In the event that the licence data received from computer 180 is identical to that currently held in the user licence directory 50, no further action is needed. If however the licence data differs there are generally two possible outcomes. In the first event the received licence data differs in that there is a licence having a full status (denoted by the status identifier "F") of which there is no record in the user licence directory 50, or the hash is not in agreement with DOI.
  • the unaccounted licence is treated as a rogue licence, the consumer is sent instructions to delete the licence data and content, and then asked if they wish to purchase a genuine copy.
  • a more common outcome of the reconciliation is that of the present example, where a licence having a temporary status T is found; in the present example the licence identifier DOI 2 QX p /T.
  • the commercial distributor saves a copy of the licence identifier in a temporary cache, and then sends an invitation to purchase a genuine copy.
  • the processor of the server 18 increments the number X stored in the content ledger 30 against the DOI of the content, in this example DOI 2 , by one, and adds the new licence identifier DOI 2 QX p+1 /F, which is unique to this transaction, to the list of user licence identifiers held against the user identifier UID B in the user licence directory 50.
  • the consumer B is then sent an updated licence identifier DOI 2 QX p+1 /F (the F now indicative of a full licence status) in a message 240, which the content management programs in the computer 84 and PDA 94 then substitute for the temporary licence identifier.
  • DOI 2 QX p+1 /F the F now indicative of a full licence status
  • the server In the event that the consumer does not agree to pay for the content, the server then asks the consumer if they wish to delete the content from their local storage, in this case their PDA and computer. If the user agrees (for example because they do not like the music which they have received and therefore do not wish to pay for it), the server communicates with the content management programs and instructs them to delete all copies of that content and all licence data related to it. If the user does not wish to pay, and does not wish to delete the content that has not been paid for, the server 18 may for example operate to deny the user access to their personal content store (described in more detail below), and, possibly following a further warning, deletes all the content in their store, all licence identifiers in their user licence directory, and cancels their user registration.
  • their personal content store described in more detail below
  • the processor 40 of the server 18 retrieves the temporary licence identifier DOI 2 QX p /T from the cache, and searches the user licence directory 50 to find the user identifier against which the character string DOI 2 QX p is stored (since as explained above on page 6, this character string is globally unique to a particular transaction with the commercial distributor Y).
  • the processor then sends a message 300 to consumer A including reward points, typically redeemable against further content when sufficient points have been accumulated, and the metadata 202 of the content the consumer is being rewarded for transmitting.
  • the commercial distributor provides further reward to a consumer in the event that they transmit a copy of the content management program to a consumer who then registers as a user with the commercial distributor.
  • a further incentive of registering with the commercial distributor, and therefore engaging in the lawful purchase and ownership of content is the ability to manage content in a more flexible manner as a result of having access to a personal content store held in the server by the commercial distributor on behalf of each of its users, in which all the content owned by the user is stored. This obviates the need for the user to have to store personally (including the necessity of providing back-up contingency) all content which he or she owns, so that instead the consumer may retrieve from the personal content store held by the server, those pieces of content which they require over any given time period.

  • references in this specification to an act performed by a party is intended to include within its scope the performance of that act by another party on behalf of the first party.
  • References to the sending of data is intended to include where appropriate the sending of a copy of the aforementioned data.
  • References to items of information technology capability (e.g. storage) being possessed by a person/organisation include that person or organisation having the opportunity to use such items or capability, and are not intended t denote any particular ownership status, nor any particular geographical relationship or physical proximity.
  • the invention has been illustrated using a PDA to store content, which connects to the network via a computer. It would however be possible to use other storage, or to connect the PDA directly to the network by equipping the PDA with a LAN car, for example.
